Detailed Documentation

The design and implementation of the PSOLA (Pitch Synchronous Overlap and Add) algorithm is a crucial task in audio signal processing. Through systematic debugging and optimization, we have successfully developed a functional version. During the design phase, we carefully considered various factors, including accuracy and efficiency in audio processing. The PSOLA algorithm implementation involves key steps such as pitch marking, segment extraction, and overlap-add synthesis, enabling time-scale modification and pitch shifting of audio signals in the time domain. This approach provides greater flexibility for audio manipulation applications. In future work, we plan to further refine and optimize the PSOLA algorithm through enhanced windowing functions and improved pitch detection methods to achieve higher-quality audio processing results.
